Apple is testing a 1.5” OLED display for use in its smart watch, according to a report in Taiwan’s Economic Times. Reportedly, the company was looking at a 1.8” display, but decided for some reason that it was too big. For comparison, the sixth-generation iPod nano contained a wearable 1.5” touchscreen. Another report from the same publication notes that Foxconn has received a small-scale order for the smart watch for about 1,000 units, suggesting that Apple will be testing the device within the company.
